Coastal1 - why run 3 inputs when two will do? Maybe I'm missing something - Unless you're using your roof cleaning pump for house washes as well? That would explain it I guess. Re: Slo Mo, I will be trying it at the beginning of our season. Historically, we've used a locally procured surfactant, as it was more cost effective than specialty surfactants after shipping. However; with this stuff working at a 1 quart to 100 gallon ratio, it IS cost effective even with shipping costs. Looking forward to trying it, and hopefully buying a 55 gallon barrel after our trial run.
There's a couple of diagrams on the old forum for a DIY version, but I suspect this would to the trick quite nicely. No need for an inverter (AC). Just tie in the 12v with an isolator. PM me or call for other options. You want to power in use, or charge on the fly while on the road? It takes a lot to run down a good deep cycle battery in a day. And if you do run it down, that's a good thing - it means lots of work got done. Best of all, there's always a spare under the hood :-)
4 gallon Top Draw backback sprayers for the stain. BTW - we used a stain product specifically made for cedar shakes. Far too labor intensive for me. We're fortunate to have TONS of asphalt roofs so we typically pass on the cedar jobs. Jeff - many shake roofs needs lots of repairs long before the client calls on us; Metal shims under the split shakes, ridge cap shakes in disrepair, end rot on shakes etc. The last one we were asked to quote was so punky, there's no way we'd even touch it.
I can't tell from your pics what the problem is. Is it residual moss? Still stained? Or as I suspect, both? Please clarify. Edit to add: temps are irrelevant, other than the process works a little slower during the application itself. ie dwell time required might be longer.
THAT is THE proper process for cedar roofs and for wooden decks and privacy fences etc. It's called "3 stepping" and has been an industry standard for as long as I've been and business, and much longer I suppose. We've done cedar roofs both ways - 3 stepping, and for clients on a tight budget, with SH. 3 Stepping produces far superior looking results. SH causes a 'washed out" look after a brief period of time. Keep in mind that 3 stepping is very labor intensive! The last one we did took us 3 full days (including staining). It had a $6000 price tag, not including the cost of the stain. Excellent research effort Jeff.
Bryan, Dickies makes a work pant that does have side, or cargo pockets (at last they did as of about two years ago). These may be the sames ones with the double thick / reinforced knee area. A bit hot in warm weather, but tough as nails. Edit - found them here http://www.dickies.com/mens-clothing/mens-cargo-pants/
I'd check a few obvious things first, if you haven't done so already: Edit to add - make sure the injector is not installed backwards! Disassemble the injector and look for clogs. Be careful if you have not done this before - little parts get lost easily.Check the draw tube for clogsTry the test with no wand/trigger or tips - just run the hose open. This creates the least amount of pressure in the line and the injector should be at full draw like this. (There is a 'cut off' with the pressure in the line, and at some point, the injector will not 'inject'. This removes the 'pressure' variable from the scenario.Working properly, you'll feel an obvious vacuum on the line with your finger tip.
If the problem is not found by these means, order a 5-8 GPM injector from Bob. I keep a few on hand. http://pressuretek.com/adamsinjector.html
